In contrast the ES scale was negatively correlated with depression and fatigue. These observations suggest that there is a partial overlap between apathy and fatigue.

Each individual’s probability of class membership was also estimated together with the overall model so that they can be placed into the appropriate class. No, PLOS is a nonprofit 501(c)(3) corporation, #C2354500, based in San Francisco, California, US, https://doi.org/10.1371/journal.pone.0169938. Project 2 examined the association between care environments and apathy in persons with dementia. Next, the six highest loading items for each factor were retained to form a revised 18-item Apathy-Motivation Index (AMI) [25]. The generally motivated class also experienced greater fatigue than the emotionally apathetic class (Fig 4A and 4C). The validity and reliability of the Turkish version of Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) in patients with mild and moderate Alzheimer's disease and normal subjects. A series of rating scales have been proposed to iden-tify and quantify apathy and to di erentiate it from other disorders, especially depression [ ]. https://doi.org/10.1371/journal.pone.0169938.g003.

[28] and scored responses using a 4-point Likert-style instead (1–4: 1 = ‘Strongly Disagree’, 4 = ‘Strongly Agree’) with higher scores reflecting greater hedonic tone. We followed Pluck and Brown [15] and Franken et al. The AMI is a reliable instrument suitable for assessing apathy and motivation in the healthy population and in clinical disorders. 9 DOMAINS 4 Composite Subscales Everyday productivity Interests Taking initiative Novelty seeking Voluntary actions Emotional responses Concern Social life Self-awareness Intellectual Curiosity Emotion Action Initiation (AI) Self-Awareness (SA) TOTAL SCORE -36 (normal) to +36 (abnormal) Lille Apathy Rating Scale (LARS) Sockeel et al., 2006 To create a comparable measure suitable for the general population, a team of clinical neurologists and university researchers developed, based on their experience with clinically apathetic patients, novel items to specifically reflect each domain of the LARS. 2019 Feb 6;19(1):35. doi: 10.1186/s12877-019-1046-x. We then labelled these classes according to their profile on apathy subtypes: https://doi.org/10.1371/journal.pone.0169938.t007. Method: Information for the IA can be obtained from the patient or from a caregiver. The new Dimensional Apathy Scale (DAS) has been specifically designed for patients with motor disability to measure 3 neurologically based subtypes of apathy: Executive, Emotional and Initiation. This raises the question of the extent to which apathy can be meaningfully distinguished from these other conditions and whether they might perhaps be associated with discrete dimensions of apathy in healthy individuals. https://doi.org/10.1371/journal.pone.0169938.t005. Serotonergic system, cognition, and BPSD in Alzheimer's disease. Key Descriptions. Finally, the AMI total score was negatively correlated with the SHAPS (r = - 0.46, p < 0.01), indicating that apathetic people experience greater anhedonia. The other subtypes were labelled ‘emotionally apathetic’ (11.9%) and ‘behaviourally/socially apathetic’ (25.3%) as they had a lower average score than overall only on that/those particular AMI subscale(s). Please enable it to take advantage of the complete set of features! Impaired social life was highlighted by Sockeel et al. To examine construct validity, correlational analyses between the overall and subscale scores of the AMI and other related measures were conducted. Apathy was assessed using the 18-item clinician-rated Apathy Evaluation Scale (AES).15 The AES was only administered at 2011 and 2015, precluding an analysis of baseline AES scores. We hypothesized that, after developing our new index, we would identify distinct subtypes of apathy in the general population and that these subtypes would be differentially associated with depression, anhedonia and fatigue. To interpret each class, we compared the conditional response means with the overall sample means on each AMI subscale (Table 7, Fig 3). 83 ALS patients, 75 carers and 83 sex-age-education matched controls participated. Whilst many tools have been developed to assess levels of apathy in clinical disorders, surprisingly there are no measures of apathy suitable for healthy people. 505 people (211 males, 271 females, 23 gender undisclosed, mean age = 28.7 years, SD = 14.9, range = 16–85, N = 27 age undisclosed), recruited from the local communities via online adverts and posters, completed a preliminary 51-item scale.
